Hi,
I have a question regarding extracting XML data as relational data. From
the looks of it looks like the OPENXML statement is not relevant since the
data I need to extract resides in XML columns (in a table).
So I have this query
SELECT [MyXmlCol] FROM [MyTable] WHERE [XmlTypeName]='Schema1'
MyXmlCol â' is an XML column, and the WHERE clause assures me that I know how
to access this XML data (using xpath)
Letâ's say the data in XML column looks like this
<MyStuff>
<Product>Windows Vista</Product>
<Version>1</Version>
</MyStuff>
(were in each row the value of the Product & Version nodes are different).
I want a table/rowset with two columns Product (xpath
/MyStuff/Product/text()) and Version (xpath /MyStuff/Version/text())
I want the rowset/table to look like this:
Product Version
-- --
WindowsVista 1
WindowsHome 2
WindowsXP 3
How do I accomplish this ?

Take a look at this example to resturn Cities
declare @.tAddress table (Address xml DEFAULT '<Address Record />' )
INSERT INTO @.tAddress (Address)
VALUES ('<AddressType name="Shipping">
<AddressRecord StreetLine1="111 Main"
City="Houston"
State="TX"
ZipCode = "11111" />
</AddressType> ');
INSERT INTO @.tAddress (Address)
VALUES ('<AddressType name="Shipping">
<AddressRecord StreetLine1="222 Main"
City="SanDiego"
State="CA"
ZipCode = "2222" />
</AddressType> ');
SELECT address.value('(/AddressType/AddressRecord/@.City)[1]',
'varchar(50)' )
FROM @.tAddress

I understand that you'd like to insert a table from a xml type value. You
may want to use openxml to do the job:
CREATE TABLE MyStuff( product varchar(20), version int)
go
DECLARE @.docHandle int
declare @.xmlDocument xml
set @.xmlDocument = N'
<MyStuff>
<Product>Windows Vista</Product>
<Version>1</Version>
</MyStuff>
'
EXEC sp_xml_preparedocument @.docHandle OUTPUT, @.xmlDocument
-- Use OPENXML to provide rowset consisting of customer data.
INSERT Mystuff
SELECT *
FROM OPENXML(@.docHandle, N'/MyStuff', 2)
WITH (proudct varchar(20) '/MyStuff/Product',
version int '/MyStuff/Version')
EXEC sp_xml_removedocument @.docHandle
select * from mystuff
If you have any comments or feedback, please feel free to let's know. Thank
you.

Thanks for the quick response, I understand the code you suggested and it

To extend your example, letâ's say I have this:

VALUES ('<AddressType name="Shipping">
<AddressRecord StreetLine1="222 Main"
City="SanDiego"

ZipCode = "2222" />

Note that the XML in the first row has two AddressRecord elements.
How do I make my result return a rowset with 3 rows representing all the
values:
SanDiego
New York
Houston
Thanks in advance!

Thank you for your response.
What I am trying to do is to extract data from an XML column I have in one
of my tables. I am trying to make the data in the XML column appear as part
of the normal rowset.
I will run a SQL SELECT statement from my C# code expecting to receive the
data back in the form of a rowset (so I can read it as primitive types using
IDataReader).
Anyway, Uri's response works for me in most of the cases, it doesn't cover
(and I tried several things myself) the case where I need to extract multiple
values (i.e. rows) from a single XML document (stored in the xml column in a
given row in my table).
Thanks for the help

The OPENXML is probably not the solution since I have the XML document
stored in a column.
As for your second solution, it looks like it is in the right direction,
however I don't see how I can scale it to the case I have N (or an unkown
number of) AddressRecord nodes in each XML document (i.e. one row's XML
column might contain zero AddressRecord elements and another row might
contain 10...)
How do I scale this solution ?

instance is a column inside a table, you use this with APPLY against the table where the column
exists. Example, assuming table is temp table instead of table variable:
SELECT nc.value('@.City[1]', 'varchar(39)')
FROM #tAddress
CROSS APPLY Address.nodes('/AddressType/AddressRecord') AS nt(nc)
